XAFS Determination of Pb and Cd Speciation with Siderophores and the Metal/Siderophore/Kaolinite System
- Notre
We provide evidence for hexadentate complexes of Pb{sup 2+} and Cd{sup 2+} with the trihydroxamate siderophore desferrioxamine B (DFO-B) at pH 7.5, and 9.0, respectively. Analysis of the species of Pb{sup 2+} and Cd{sup 2+} adsorbed at the surface of kaolinite clay under the same pH conditions and in the presence of DFO-B indicate that Pb{sup 2+} is sorbed as a metal-siderophore complex while Cd{sup 2+} is not.
